problem with makemigrations

[JohnnnyBeGood]

thanks for this example!

when I was doing this code, the compiler generated an error
"TypeError: init() got an unexpected keyword argument 'on_delete'
"
then I added to all lines where there is a "... = models.ForeignKey(......)" entry: "on_delete = models.CASCADE"

thereafter " pyhon3 manage.py makemigrations 'mysiteblock' " completed without errors and created the migration file 0001

thanks.
